Gadget everywhere,iPad, iPhone, notebook, Netbook

September 2nd, 2010 admin No comments

What did you say? Is the tipping aim in favor of having too many gadgets? Well, it depends.
MacBook, iPad 3G, iPhone 3GS, and Windows laptop. The ‘essential’ associates with the aim of travels with me. How many is too many?
Original, assent to me count the ways I can live connected: A connect of MacBooks, an iPad 3G, an iPhone 3GS, an old HP tower, and, if I need it, a BlackBerry Storm 2 (though Wi-Fi access lone in favor of the BlackBerry, such as I recently discontinued service). With the aim of covers the largest part of what did you say? I utilize everyday. (And I know make somewhere your home with the aim of add a Netbook to a analogous mix of policy.)
Of line, I got to this state of surplus voluntarily. Not a soul held a gun to my be foremost. With the aim of whispered, on the largest part days–in myriad ways I won’t perform into here–this associates of policy enhances productivity and sustains the computer-related hobbies I contain.
But on the bad days it’s get-thee-to-an-IT-department–at smallest amount, that’s the feeling. Compounding glitches can bang precarious majority in the sphere of minutes.
Does the following, or else a distinction of the theme, sound familiar? The Internet connection goes south, freezing the browser and the 15 or else so tabs with the aim of are straight. And the Windows structure is pestering you with reference to a massive precarious revise while a message is effective you it can’t link up to the laser printer. The wireless laser printer disconnects strangely. Meanwhile, iTunes crashes on the iPhone. And the iPad 3G runs old hat of juice in the past few minutes once you need it. Oh, and the cable gentleman (in this occurrence, the AT&T IP guy) is knocking on the exit for the reason that he wants to check the fiber-to-the-node connection by your accommodate.
And this brings us to the iPad. With the aim of is the X reason with the aim of didn’t exist in the past. So, is the iPad the tipping aim? I would say rebuff. The iPad is in point of fact relatively innocuous, I think. While a Windows structure can live a ticking era bomb of crash-happy applications requiring–depending on how bloated the PC is–user omission to keep things from exploding, the iPad, in the sphere of my experience, has minute overhead (beyond charging the battery).
You don’t need an IT gentleman to illustrate you how to shift photos to your iPad. You complete need (or, in the sphere of my occurrence, would like to have) an IT gentleman to get a hold you old hat of a Windows blue-screen-of-death sphere each era you start up a special use. (One of my tackle, by the way, still runs Windows landscape in favor of reasons I won’t perform into at this time.)
So, the doodad overload occurs once you contain too many policy with the aim of require a disproportionate amount of era fixing, configuring, and updating relatively than productive utilize.
Of line, a hush-hush doodad superfluity can occur, I suppose, by in the past few minutes having too many policy. In the sphere of with the aim of occurrence, straightforward things like frustrating to plan the recharging of all of the batteries in the sphere of laptops, smartphones, and cameras can trigger soul searching and philosophical quandaries with reference to how crucial know-how really is (not to reveal the environmental impact).

Google Android news:

Google released a new operating system every time after the generation of various mobile phone manufacturers to upgrade the operation will be put on the agenda, there would be a next-generation operating system out of the news on the Internet, such as Google in the form of gradually promoting Android operating system, a various practical ways. With the release of Android3.0 system gingerbread, various mobile phone manufacturers are busy all the system’s own Android mobile operating system upgrade to Android2.2 time, foreign media, news that the name of Android the next generation of systems have been identified, the series code HoneyComb, translation from Chinese is “honeycomb”, characteristics of the operating system and the minimum allocation of no news.

Android’s naming history

Familiar with Android’s friends all know that Google has always been the name of love for dessert named for the Android operating system. Android1.5 operating system was ordered CupCake, CupCake is the girls prefer a cup cake or buffet in the room where the cake is more common. Android1.6 operating system called Dount, that is, the movie “Transformers” fat hackers at the trial eat donuts. Was named in Android2.0/2.01/2.1 Eclair cream sandwich bread. Now that mobile phone makers are upgrading Android2, 2 operating system, called Froyo, is called frozen yogurt desserts. In the recently published Android3.0 called Gingerbread, is a small biscuits called gingerbread. Foreign mass media in just burst out of Android the next generation operating system HoneyComb, How about I not yet found the desserts, so the Chinese interpreter for the hive. Users are also welcome friends broke the news HoneyComb what kind of dessert, I will be in the form of text description and screenshots will be published in the article, your thoughts within, in order to express your gratitude.

Gingerbread operating system on Android3.0

System standby, sleep , sleep differences , advantages and disadvantages

August 17th, 2010 admin No comments

Windows operating system very early on the standby , sleep mode and so on , but it is Windows Vista, adding a new mode called sleep , but many people still used when not in use the computer to completely shut down . In fact, take advantage of these models , we can not only save power consumption , you can also use the shortest possible time to get the system back to normal working condition.

These three models are defined as follows :

  Standby

The system switches to the mode, in addition to memory , dell inspiron 1525 battery,computer power supply other equipment will be suspended and only the memory of which rely on electricity to maintain the data ( because the memory is volatile , as long as power , data , there is no ) . This time when want to restore , you can return to standby before the state . This model is not completely consume , so if power in standby mode exception occurs (such as power failure ), then the next can only reboot , so standby before the unsaved data will be lost. But this model is the fastest speed of recovery , the general can be resumed within five seconds .

  Dormancy

The system switches to this mode , the system will automatically dump all the data in dell inspiron 1318 battery  memory in a hibernation file on the hard disk , and then cut off the supply of all equipment . Such as recovery time , the system will hibernate files from the hard disk content directly into memory , and return to the state before sleep . This model do not consume , so afraid of sleep abnormalities after the power supply , but at the cost and the need for a physical memory as the size of hard disk space ( Fortunately, the hard disk now has crossed the TB level , and large-capacity hard drives getting cheaper ) . The slow recovery of this model , depending on memory size and disk speed , generally have about 1 minute or even longer .

  Sleeping

Windows Vista is the new model that combines all the advantages of standby and hibernate . Switch the dell vostro 1310 battery system to sleep , the system will dump all the data in memory on the hard disk hibernation file (this similar to hibernation ), and then shut down all equipment in addition to memory outside the power supply , so that the data is still maintained in memory With (this similar to the standby ) . Thus, when we want to restore the time , if sleep did not happen during the abnormal power supply , you can directly from the memory data recovery (similar to standby ) , very fast ; but if the power supply abnormalities during sleep , memory The data has been lost , you can restore from the hard disk (similar to hibernation ), but the speed will slow down . But in any case , this model will not lead to data loss.

Because there are so many benefits of sleep function , so vgp-bps8 Windows Vista Start menu power button default the system will switch to sleep mode . So we can take advantage of this new feature, after all, to resume from sleep mode , the speed much faster than start from scratch . And has been conducting sleep mode is not go on , if the system into sleep mode for some time after ( Juti time can Sheding ) not wake up , then Huanhuizidong be Zhuanru dormant, and the memory Gong Dian Guan Bi , further savings Neng Consumption .

Stark: General Motors R & D investment in battery-protection core competence

August 2nd, 2010 admin No comments

In fact, Stark told the forum for General Motors, the battery on the field of technology and R & D is a core benefit of competitive and General Motors in battery technology have also made many investments, but also very concerned about the new battery technology that allows us to have a better energy supply and improve the capacity of the battery and so on. Of course, to secure the future of electric vehicles have a successful development, really need to understand the battery technology right, but also a good command of the battery technology, indeed this is happening to drive the battery a very important source of energy, but GM technology stack is the head side. Stark said that compared to competitors, General Motors, especially with the electric vehicle technology R & D base competitive advantage. hp compaq 6910p battery hp compaq 8710p battery 

GM Chevrolet Volt on the current-carrying cell lithium-ion battery with the general global supplier Compact Power Inc. (South Korean manufacturers LG Li-ion batteries in North America, a subsidiary of chemical company) to offer if it means that GM will not in future electric vehicle research and development of the basic technology issues, Stark said that GM has not abandoned the basic technological research and development. R & D in battery technology, GM has its own testing center, has also invested heavily in related fields of research.

In addition, Stark also said that the development of electric vehicle technology is not limited to the battery, research and development of battery technology is only one direction, but it was not only represent the future direction of the only GM technology is also different in other investments but also, and close collaboration with suppliers, improving the ability of General Motors. General Motors in the other, such as control systems, chassis, etc. R & D has put a lot of manpower and resources. Therefore, in research and development if it is hybrid, plug-in hybrids, and wide-range electric vehicle (for example, Chevrolet Volt), the pure electric vehicles or fuel cell vehicles General Motors have invested in core technologies such enormous resources dedicated to providing consumers the best vehicles in the world, R & D is concerned, General Motors core competitive advantages. dell studio 1535 battery dell vostro 1310 battery 

To better support the development of these core technologies, Karl Stracke announced at the Forum, General Motors released BEV (Battery Electric Vehicle) battery electric vehicle test program, which in different countries through a variety of different models of battery technology to be tested. The test will provide the practical application of data around the world, including driving habits, the battery capacity, market demand and consumer acceptance of electric vehicles likely to significantly increase the competitiveness GM’s electric field of automotive technology. dell xps m1530 battery  xps m1730 battery

Electric vehicle driving mode change problem, Stark said, GM has developed the strategy of the most advanced driver technology. Compatible with this strategy, GM has committed to a series of advanced research and development. For example, the mode of transmission of power motor is a battery-powered motor and transmission to the wheels, this approach is a loss of energy. General Motors is working on battery-wheel drive so direct. power flows from the point of view, this can indeed improve the effectiveness of training, but current research shows that this approach only from the point of power transmission efficiency of view it is an advantage. This technology is still under discussion, two weeks after General Motors will hold workshops in the United States, Michigan, on the exploration of pure power electric cars energy flow depth. vgp-bps8

New batteries hot: thin film solar cells

July 28th, 2010 admin No comments

Concept is gaining popularity as a low-carbon, the battery can lead to a growing concern.

The batteries and pollution

The batteries pollution potential has attracted considerable attention. China is a global leader in the production of a battery and energy consumption, has information that China currently has more than 1,400 battery manufacturers, production capacity of the battery in 1980 compared to U.S. U.S. and ranks first in the world. Production of dry batteries in China in 1998 reached 14 billion, while total world production of dry batteries is approximately 30 billion dollars. dell xps m1530 battery dell vostro 1510 battery

Such a large number of batteries, which makes a big problem is exposed, is the amount of pollution that the batteries are not destroying our environment. If the first cell on the ground rotting, it’s toxic substances can make a square meter of land lost value, throw a coin cell in the water it contains toxic substances that cause pollution of 600,000 gallons water in the body, the water equivalent of a person’s life; batteries contain cadmium, lead, mercury, nickel, zinc, manganese, cadmium, lead, mercury is most harmful substances from the human body. hp compaq 8510p battery sony vaio vgn-fz battery

Therefore, the collection and disposal of spent batteries is very important, if you throw badly, perhaps on the ecological environment and serious harm to human health. Although the technology has given us the right direction, but my battery is not optimistic pollution phenomenon. Currently, most of our garbage is mixed with used batteries to be buried, over time, after conversion to rotting of the battery, the leaching of heavy metals, both can contaminate groundwater they can contaminate soil eventually, through various means in the human food chain. biological uptake of heavy metals from the environment through food chain biomagnification, step by step in higher organisms, thousands of times richer, and then enter the human body through the food chain, resulting in savings certain organs of chronic poisoning, Japan Minamata disease is a typical case of mercury poisoning. sony vgp-bps13 battery

Thin film solar cells Cheng Xinchong

When war internal battle when the party polysilicon thin film solar cells already open seats silently. field production of photovoltaic electricity, the two main “master” cells, crystalline silicon and thin film batteries, seems to draw a contest.

As its name suggests is the layer stack of thin film solar cell thin film silicon is extremely rare and easier to reduce costs, while it is both energy-efficient products, but also a new type of building materials, more easily with the perfect combination of architecture. raw material of silicon on the international market in the context of continuing tension, thin film solar cells has become the international trends of PV market development and hot spots. asus eee pc 1000he battery

Although thin film solar cells have already appeared, but the conversion efficiency is low, attenuation rate were higher, some years ago was not enough to attract the attention of the industry, market share is low. With the continued progress of its technical efficiency of photoelectric conversion 的 been enhanced to Xianzai Nian Bi 2 ago about an improvement of 30% -40%, and silicon cells based Suiranrengran Jingtai big gap, but its use, simple process Liaoshao low energy consumption, costs of certain benefits, more and more accepted by the industry.

Corresponding to this, depending on modules hot sun, the fever of polycrystalline silicon thin film photovoltaic array has become the hot new investment.

Compared to crystalline silicon cells, thin film batteries is much greater potential for cost reduction through rapid technological progress in thin film batteries. Thin-film solar capacity may be the next to reach 20% of the entire solar industry, while just 7.6% in 2007, shows that among the space. dell studio 1535 battery

What is a Flash cache?

July 21st, 2010 admin No comments

A Flash cache acts like SRAM memory caches that are designed to speed up DRAM access times; Flash caches speed access to HDDs in an analogous manner. Data is drawn from HDDs as needed and the retrieved data is cached in NAND Flash. The next time this data is needed, it’s drawn directly from the cache instead of the slower HDD ( dell inspiron 1525 battery ) .

Flash caches do not require as much NAND Flash memory as SSDs, and therefore cost less, but they can deliver significant performance improvements when paired with HDDs—in fact the effective performance of a Flash cache paired with an HDD can actually exceed that of an SSD ( dell latitude d830 battery ) .

(Note: It’s also possible to use DRAM to cache HDD data, but DRAM is more expensive than NAND Flash for equivalent capacity and DRAM provides only volatile storage unless you add a backup battery. For these reasons, NAND Flash is the better choice for an HDD memory cache .

Using a faster memory technology as a cache for a slower-yet-cheaper memory technology is a relatively common technique used by computer designers. Designers have always faced memory access-time problems and caching is a very, very common solution to this problem .

If the typical working set is a small fraction of the total HDD capacity, then a cache that holds that working set will make the HDD appear to be as fast (or almost as fast) as NAND Flash memory, resulting in a dramatic improvement in application performance( sony vgp-bps9 battery ) .

Adding a cache can deliver significant performance gains for I/O-intensive workloads but it’s critical to make the cache invisible to the application to avoid rewriting the application code. You make a Flash cache invisible by intimately integrating it into the operating system and the file system (sony vgp-bps8 battery ) .

This is a critical step because it sidesteps the need to rewrite the application so that it need not decide what goes where. Application code must explicitly manage code and data placement in storage when a system employs a mix of HDDs and faster, Flash-based SSDs but not if the Flash memory is configured as a cache .

If you can write or rewrite an application so that it explicitly controls where data is stored, then a mix of SSDs and HDDs can be used effectively. NAND Flash cache used to accelerate HDD performance solves a more common problem—a problem ingrained in all existing application programs that are not written for an explicit SSD/HDD storage hierarchy .

The question is: Is there a practical working set that’s a small subset of a computer’s total disk capacity? Intel’s Amber Huffman presented some very interesting data in 2008. Intel tracked five employee power users and observed how they used data over successive time periods ( vgp-bps8 ) .

Four out of five of these power users used no more than 6 Gbytes of data for a working set in a typical 10-hour work period. A 6-Gbyte NAND Flash cache is easily and economically achievable today. It’s not an incredibly expensive amount of NAND Flash memory ( hp compaq 8710p battery ) .

With the right parallelism designed into the cache, you can get the required access time, throughput, and capacity to make a huge improvement in application performance by masking the HDD’s access time with a relatively small Flash cache

Here’s a different example from the Enterprise world that demonstrates the advantages of using Flash memory to cache HDD storage. Pliant Technology, a vendor of high-speed Flash Enterprise SSDs, studied a typical data warehouse. The company compared high-end disk arrays composed of fast, enterprise-class, short-stroked HDDs against a hybrid array of four SSDs and many low cost HDDs (not short-stroked ).

Pliant’s hybrid drive array dramatically increased available disk capacity and performance versus the conventional short-stroked HDD array. The disk capacity per rack shelf increased by almost an order of magnitude, while the IOPS performance increased 6.5x .

Note that the cost per rack shelf also increased significantly, but this increase was compensated by a corresponding decrease in the number of shelves required for storage. The key figures of merit for this example ( sony vgp-bpl8 ) :

total storage-system cost decreased by 50%

cost per IOPS decreased 50%

the cost per gigabyte of storage improved, and

the hybrid disk array required one eighth the power to operate and cool compared to the amount of power needed to operate and cool the array of fast, short-stroked HDDs—nearly an order of magnitude improvement in power consumption ?

So NAND Flash memory used as a disk cache whether for low-end applications or enterprise installations shows great promise.

AT&T’s weak spots is shown by IPhone signal bar fix

July 18th, 2010 admin No comments

Two weeks in the past, Apple promised it would soon back copy a put back into working order on behalf of the “totally wrong” software formula it has been using on behalf of three years to spectacle the iPhone’s hint at strength. Apple on Thursday released the iOS 4.0.1 keep informed with a put back into working order on behalf of the bug. We instantaneously dove in vogue.

Apple has dramatically untouched the hint at strength to hint at get in the way mapping in vogue the original software, making the dynamic range not no more than much broader, but the range ideals on behalf of every get in the way much wider. The range of signals so as to correspond to bars three and four are the same width, and get in the way two is no more than a little not as much of.

The stop quantity in support of dropping from two bars to lone restrict remains the same, but each other quantity has increased. That’s an of great consequence adjustment: In the sphere of our opening investigation of the iPhone 4 satellite dish, we recorded a worst-case indication leave out of around 24 decibels once the iPhone 4 is held tightly in the sphere of the missing dispense — supplementary than on the iPhone 3GS or else competing phones like the Nexus lone. We concluded with the aim of with the aim of the sound effects of the indication leave out were exacerbated in the sphere of part by the way the iPhone visualizes indication strength. Its dynamic range is compressed so much with the aim of the 24 dB leave out from the so-called “death grip” may well succeed all the bars shot away.
But with the new to the job software, if you give birth to five bars on your screen, the worst-case leave out of 24 dBm rebuff longer makes all the indication bars disappear. It as a replacement for drops down to two bars. Apple’s mappings give birth to passed on from having probably the most-compressed dynamic range surrounded by handset vendors to a smaller amount compressed than machine.
In the sphere of other lexis, Apple’s indication strength coverage is at this moment far supplementary straightforward.
While the software revise perceptibly does not and cannot lecture to the design of the satellite dish itself — or else succeed the indication leave out from holding the phone at all a smaller amount — it does amendment the way the publication is perceived. The largest part iPhone users command consider it fewer bars disappear once they regard the iPhone 4 in the sphere of a bare dispense. The wall effect is with the aim of the iPhone at this moment displays fewer bars in the sphere of the largest part seats, and users command in the sphere of clock consider it the — perhaps a crumb shocking — truth of indication strength in the sphere of locations previously denoted having the status of having admirable service. Apple (AAPL, affluence 500) is simply free to ban cover in support of AT&T’s (T, affluence 500) meet people.
Apple has besides, having the status of promised, misused the heights of bars 1, 2, and 3. They’re taller, and the consequence is with the aim of the next of kin heights are rebuff longer linear, but relatively a bit exponential looking. It’s a mind trick with the aim of Apple rebuff doubt hopes command succeed the indication look better. If the bars are taller, they have to denote stronger indication, true?
The truth is with the aim of Apple likely wants to redirect by smallest amount various of the opening backlash AT&T command look in support of coverage the indication bars with no at all concessions. Apart from of how tall the bars are, near are still free to be present fewer of them to all intents and purposes in all places. Interestingly a sufficient amount, while bars 1 and 2 are the the largest part misused visually, their respective cutoffs are to all intents and purposes unchanged.

Lithium battery cars and foreign Rush

July 14th, 2010 admin No comments

New energy automotive industry’s rapid development, led the domestic auto business investment boom lithium batteries, and battery manufacturers are multinational companies with vehicle joint venture, signed a supply contract or cooperate with the auto parts manufacturers access to customers and other into the Chinese market. 

Compared with foreign-funded enterprises, Chinese enterprises have the capacity, the industry chain, and policy support has some advantages, but the foreign-funded enterprises in the core materials, product segmentation, production process, more mature. The future, other countries, the excess capacity lithium battery car will accelerate to enter China, the face of fierce competition and has just started the domestic auto battery market, domestic manufacturers and vehicle manufacturers should strengthen other industries outside the chain of cooperative R & D enterprises, while diversified breakdown products. 

China’s auto market situation lithium batteries Inspiron 1525 battery  

    New energy vehicles battery [1] mainly nickel-hydrogen batteries and lithium batteries, nickel-hydrogen battery at present China-developed hybrid vehicles, lithium battery vehicle development still in its infancy. Ni-MH battery manufacturing hybrid vehicle is classified as a mature product, allowing use in nationwide sales, while the lithium battery manufacturer’s hybrid, pure electric cars are only a limited area trial (2010) [2]. As the high cost, large size lithium VGP-BPS8  battery is still mainly used in electric bicycles and public transport vehicles.

    BYD, BAK, power of God and other domestic companies have started production of automotive lithium batteries. Lishen miles with U.S. joint venture company for the U.S. to provide Coda brand car batteries, the order of about 2010, 3000. BYD introduced in 2010 on the use of E6 electric car batteries to their production Hp Compaq NW8240 battery .

    In the Chinese market, the potential has not yet released automotive lithium batteries, yet can not say with overcapacity. And non-plug-in hybrids compared to power plug-in hybrid vehicles and pure electric cars to the greater demand for lithium batteries. Chinese companies to actively promote the use of lithium battery electric vehicles, pure electric vehicles in China is expected to become the fastest-growing country. January 2010, the public Motors 2008EV electric car market, in addition, BYD E6, Chang BenBen i, Qi Rui Ruiqi M1-EV, Hafei leopard and other game plans electric cars in the domestic market in 2010. 

    Canada strongly supported the national electric cars, plug-in hybrid development, recently began large-scale domestic car charging station building, which have contributed to the growth of automotive lithium battery market. The current cost of lithium battery is about 3000-4000 yuan / kWh, and the new introduction of state subsidies on pure electric passenger cars and plug-in hybrid vehicle subsidy standard is 3000 yuan / kWh. Ni-MH battery is the non-plug-in hybrids mainstream, but if the costs can be reduced, lithium batteries are also expected to be further applied to non-plug-in hybrid vehicles, many vendors have been intended. Changan Automobile since the second half of 2010 will make its hybrid vehicles use nickel batteries used lithium ion batteries Sony VGP-BPS9 VGP-BPS10 . 

Foreign enterprises to enter the domestic market vehicle lithium manner

     Foreign battery makers and domestic enterprises to establish joint venture development vehicle of pure electric and plug-in hybrid cars. The development of such cars has just started to pay more R & D costs, take more market risk. SAIC and the lithium battery maker A123 System, a joint venture company vehicle battery system. SAIC plans to end 2012 general hybrid cars, by the end of 2012 launch plug-in hybrids, and launched in October 2012 of pure electric vehicles. South Korea Li-ion battery maker SK Energy, Korea Electric car maker CT & T Inc. [3] and Beijing, China Motor Corporation will establish a joint venture to produce and sell electric cars in China. Beijing Automotive’s new energy automotive technology lines to develop electric vehicle based. 

    Motorcycle, electric bike started the domestic auto makers, the lack of vehicle design and manufacturing experience, but also an urgent development and manufacturing experience with electric cars lithium battery manufacturers foreign auto joint ventures. May 8, Zongshen Power Battery Company and the Boston signed “Memorandum of Cooperation”, the two sides will power the battery pack and power systems integration to cooperate, the two sides plan to set up joint venture in Chongqing. 

    Weak hybrid systems [4] The development has been relatively mature, there are models in the hybrid system to load the weak domestic manufacturers of many strategies the next few years, bringing a large number of batteries purchased. Changan Automobile: In 2012, all own brand products to achieve the weak degree hybrid, and LG Chemical Co., Ltd. will provide assembly in Changan Automobile hybrid car batteries. SAIC upcoming year, “weak hybrid” cars Roewe 750 with a Johnson Controls-Saft’s lithium Hp Compaq 8510W battery

    Li-ion battery manufacturer EnerDel and domestic auto parts maker Wanxiang Group cooperation, access to special areas of electric vehicles. The two sides will set up joint venture production of automotive batteries and battery systems, one of the objectives is the universal heavy-duty truck customers. Universal car parts in the field of heavy experience with a number of heavy vehicles manufacturers have a good partnership, and with the power battery development is also very interested in, and EnerDel’s main goal is to China’s heavy-duty car battery market. Currently the application of lithium batteries in the car, little heavy, but also in traditional power systems experience. 

    Combining the characteristics of local industries in China, also plans to build Boston batteries lithium diverse plant products. Boston lithium Dell XPS M1330 battery company’s production base in Chongqing, including not only the cause of car batteries, but also supplied to Chongqing enterprises in lithium battery electric bike, and the supply to the HP factory in Chongqing, the consumer electronics business with a lithium battery. 

Comparison of the competitiveness of Chinese and foreign enterprises 

    Domestic enterprises in battery technology, and the battery management system, production process, there is still to be improved. Most cell companies do not have the domestic battery management system independent design and development capabilities, domestic battery management system developed in isolation on small-scale enterprises, and many other non-university research institutions and production quantities. Single battery car battery needs to be integrated, the key is to ensure the consistency of the battery. Although many domestic enterprises have production experience in lithium thinkpad x60 battery, but the manufacture of car batteries required for battery combination and consistency of the production process does not depend on the scale of investment and upgrading can be quickly obtained. Current pure electric vehicles, plug-in hybrids are small-scale pilot projects, large-scale production may experience problems. Nissan’s product consistency lithium technology took decades to finally complete. 

    More domestic enterprises to produce lithium-ion battery for electronic products started, extensive product portfolio, but the breakdown products of foreign companies to do better, can be targeted into the market. EnerDel, A123 system, SK Energy and other companies have set up a perfect power battery system, covered truck, aviation equipment, passenger cars, etc., and there have been various types of new energy vehicles for the characteristics of the VGP-BPS8  product line. 

    Chinese enterprises in the lithium battery industry chain has certain advantages, but the core components of the edge area of foreign enterprises. Relatively complete industrial chain of China Li-ion battery, domestic enterprises have long-term cooperation in upstream and downstream to form a stable relationship. BYD’s investment has been involved in battery industry has many elements, including core products cathode materials, electrolyte and battery components, automobile manufacturing, in addition the company has built power stations, and lithium ore resources in the study. The core material LiPF6 lithium electrolyte were Japanese and Korean business monopolies, domestic production of lithium battery separator has just begun. SK Group in the production of lithium-ion batteries VGP-BPS8 have gained considerable experience. 

    Government support may become the biggest advantage of battery manufacturers. 2010 state validated enterprise technical centers, including car batteries for the first time the scope of research and development. Forthcoming “new energy vehicle development plan”, the key parts localization rate may become important. 

Prospects and recommendations 

    Other countries, the excess lithium capacity to enter China as soon as possible, intensified competition in the domestic market. Lithium power battery in Japan may have a lot of excess capacity. Many foreign battery manufacturers have stability in the international cross-border vehicle partners, these vehicle partners in China has launched a vehicle business, through their channels, will soon enter the market. 

    Speed up the domestic car battery to establish a unified standard. If every vehicle battery manufacturers have different standards, with initial orders for small, battery manufacturers is difficult to scale. Although the market has just started, the standard set up is very difficult, but needs to play a role in the League, to discuss the direction of development. 10 Chinese automakers formed an alliance made up of the standard T10 Working Group, jointly develop components for electric vehicles and vehicle standards. 

    In addition to vehicle manufacturers, the future of the domestic automobile manufacturers should also strengthen the lithium battery industry chain and R & D cooperation of other manufacturers. Compared with ordinary lithium batteries, lithium battery production car on the purity of raw materials, quality requirements are high, while domestic manufacturers of raw materials in many lithium battery just entering the field. In order to improve battery life mileage, in addition to start from the battery itself, but also can optimize the body material, to improve efficiency, driving motor to achieve, and these areas also need to improve domestic technology. 

    Passenger demand the release of lithium batteries will take some time, large-scale mass production there are some difficulties, firms should diversify product segments, to pursue other market opportunities. As consumer habits, costs, and infrastructure and other reasons, the popularity of electric passenger vehicles will spread slowly, while public utility vehicle market due to the Government to promote more likely to develop. In addition to motor vehicles, power lithium battery can be applied in many fields, such as network storage market. China’s first wind, and optical storage can be integrated demonstration projects to start the first quarter of 2010, plans to invest 20 billion yuan total, BYD Li-ion battery energy storage has won one item 1MW

Battery hog compare between the Windows and OS X

July 9th, 2010 admin No comments

One of the best reasons to get a new Hp Compaq 8510W battery  , aside from the dazzling new screen on the 13-inch, and in spite of the SATA capping that’s apparently in place, is the extended battery life courtesy of the new built-in lithium polymer batteries. And by all accounts, even if you won’t necessarily reach Apple’s estimates, you will get more usage out of your notebook without having to connect to a power source. Or you’ll get more usage as long as you’re not running in Windows under Boot Camp, that is.

AnandTech’s Anand Shimpi has been running a Hp Compaq NW9440 battery through its paces over at his site, and while he was very impressed with the machine’s new battery overall, he noticed a considerable disparity between apparent power consumption under OS X, and under Vista. Nor was the difference marginal. Running OS X while only web browsing, Shimpi was able to coax a little over eight hours out of the notebook under OS X, and only six using Vista. That’s a two hour, or 25 percent difference.

Windows 7, which is supposed to make up for a lot of the mistakes Microsoft made with Vista, fared no better. The RC 1 version of the upcoming OS lasted only 5.48 hours using the same test conditions. Some of that can be ascribed to there not being final, optimized drivers for Windows 7 yet, but I doubt that accounts for the more than two-hour VGP-BPS8  life  deficit it has compared with OS X running on the same hardware.

Windows supporters will no doubt chime in with claims that the Apple hardware is to blame, but Shimpi found some reason to believe that may not be the case. He spoke to a number of PC OEM manufacturers to see if they’d found a difference in acer aspire one za3 battery life between OS X and Vista, and though none would officially go on record, some at least admitted to seeing a similar difference to the one Shimpi had found.

Since Apple doesn’t officially support any third-party hardware, it’ll be hard or even impossible to prove that OS X is, in fact, a more battery-efficient operating system, completely independent of any hardware considerations. Still, that’s one less reason to ever commit sacrilege by dual-booting your Apple notebook, which is bad news for Windows sales, no matter what the cause.

All you hackintosh experts out there, feel free to chime in with your own Dell Vostro 1310 battery  life tales, since your experience running OS X on non-standard hardware might be the closest thing we can get to a fair standard for comparison.
